Background and Aim: Many studies have shown that various fluoride-containing products can change salivary fluoride concentration. Nowadays, different kinds of topical fluoride gels and foams are used to prevent dental caries. The aim of this study was to evaluate salivary fluoride concentration following the application of 3 different fluoride containing materials at different follow-up interva...

BACKGROUND Although application of professionally applied Acidulated Phosphate fluoride (APF) gel is effective in prevention of dental caries, APF-induced discolouration and/or surface degradation of dental restorations has been reported. However, no publication has reported a dose-response effect of APF gel on Glass Ionomer Cement (GIC) restorations in vivo and/or human teeth. Therefore, this ...

Some topical fluorides cause surface changes in dental materials. The purpose of this study was to compare the effects of a topical acidulated phosphate sodium fluoride (1.23% APF) foam with the effects of other topical fluorides on the surface of veneer porcelain. Forty porcelain specimens (Ceramco) were placed into eight groups (N = 5). Four groups were immersed in either 1.23% APF foam, 1.23...

This in situ crossover and blind study was conducted to investigate the effect of professional acidulated phosphate fluoride (APF) gel application time on the subsequent inhibition of enamel demineralization. During 3 phases of 28 days each, 15 volunteers wore palatal appliances containing 4 enamel blocks, which were subjected to 3 treatment groups: not treated (control) and pre-treated with AP...

AIM The aim of this study was to evaluate the surface/mineral changes on enamel before and after the application of acidulated phosphate fluoride (APF) gel, fluoride enhanced hydroxyapatite gel and propolis in conjunction with carbon-dioxide (CO2) laser. MATERIALS AND METHODS Crowns of 40 human maxillary central incisors were collected and were divided into four groups of 10 each: Topical flu...

OBJECTIVES The aim of this study is to determine the effects on remineralization of a novel iontophoresis device called 'Fluorinex', conventional (acidulated phosphat fluoride) APF gel treatment, and conventional ionthophoresis device comparatively by laser fluorescence measurements. STUDY DESIGN Artificial incipient carious lesions were created on immature, 60 intact premolar and molar teeth...

The purpose of this study was to compare the oral fluoride (F) retention following acidulated phosphate fluoride (APF) foam and gel applications in children. Fifty-nine children were divided into two groups, 6-9 years old and 10-13 years old. They each received a randomly assigned sequence of topical F foam and gel applications in two consecutive visits, using either sponge-lined or unlined tra...

This in vitro study evaluated the compositional, crystalline, and morphological effects promoted by Nd:YAG laser on root dentin, and verified the effects of laser and topical acidulated phosphate fluoride application (APF-gel) on dentin erosion. 180 bovine dentin slabs were randomized into 4 groups (n = 45): G1-untreated, G2-APF-gel (1.23% F-, 4 min), G3-Nd:YAG (1064 nm, 84.9 J/cm², 10 Hz), and...

PURPOSE The purpose of this in vitro study was to evaluate the effect of low-fluence argon laser (AL) irradiation and acidulated phosphate fluoride (APF) gel treatment on enamel microhardness. METHODS Twelve mandibular permanent molars were selected for this study. The teeth were sectioned generating 4 flat enamel surfaces per tooth. The flattened enamel tooth surfaces were randomly assigned ...
